The spectroscopic orbits for the primary and secondary components of V 380 Cygni have been redetermined by cross-correlation techniques. New masses and orbital elements differ only slightly from those published previously by Batten (1962). However, the spectroscopic data allow the presence of apsidal motion contrary, to previous interpretations. Relative radii, temperatures and orbital inclination have resulted from a solution of three independent light curves. When combined with the spectroscopic data they yield physical dimensions for the component stars, a chemical composition of (X, Y), (0.66, 0.30) and a system age of about 8 million yr. In about 500,000 yr the primary will reach the inner Lagrangian surface and the system will begin the mass-transfer phase of its evolution. Theoretical and observational apsidal periods near 1500 yr are in good accord.
